I sent an EMail to their Corporate Customer Service about a month ago at We_Can_Help@cable.comcast.com . I didn't receive a reply. Probably need a bunch of Emails regarding this issue for them to take this seriously.

I know they take emails to that address seriously, but it depends on if you have a local corporate office or not. I sent an email to that address yesterday regarding a picture issue and received a phone call today from Comcast. The corporate office for NJ is about 20 miles away though. The person wasn't particularly helpful, but he did give me his direct contact info.

I'd say try again or try to find if there's a corporate office in your state.

My Comcast head end is in Bonita Springs, FL. The Fort Myers area. The update is a result of pestering Comcast engineering every day since Monday. It's not part of a general rollout.

As of now, I have all six tuners working. It remains to be seen if this holds. Additionally, this firmware upgrade is supposed to fix some pixilation issues. I experienced some serious pixilation. I hope that is resolved as well.

I just bought a Roamio Plus, and stopped by Time Warner (Rochester, NY) to pick up an MCard and Tuning adapter. I specifically asked the tech in the office if the Mcard can support 6 tuners, he said "I don't see why not". He wasn't aware that Tivo had 6-tuner models, and I am suspect if Time Warner can support 6-tuners.

Is there anything obvious I should look at before I install the card that might tell me it is capable of supporting 6 tuners?

I think he's referring to an updated 1.5.2 version. A lot are on older versions of 1.5.2. Not even sure Comcast is aware of 1.5.3.

Ah, okay. Well, an updated 1.5.2 version probably won't make a difference. Everyone that I talk to at Comcast tells me that 1.5.2_3001 is the latest version that they have. If they're not even aware of the 1.5.3_1101 version, it will probably be a long time before they're ready to do a widespread rollout.

Good news for TWC subscribers, as they seem to have gotten on board the 6-tuner bandwagon. I contacted the TWC support site, and was told "Yes, we have verified that our Multistream cards will work with the 6-tuner TiVo".
